PHYS 1433 Lab 2: Measurements and Densities, Due September 21 09/19/23 Lab report checklist Sections of the report: Objective Theoretical background Procedure Analysis, graphs Sample calculations Conclusion Questions from the manual Objective : To determine the relationship between (in.) and (cm.) as well as cubic in. & cm. Density will also be determined using the vernier caliper and triple beam balance device. Theoretical Background: In the experiment it is helpful to use a consistent set of metric units when following each instruction such as the SI, international system. Conversion factors were also utilized as instructed, to convert from one set of units to another we use a conversion factor, factor as followed: 1 in= 2.54 cm 1 in 3 =16.39 cm 3 . Other formulas included in this experiment include that of volumes: Volume of Sphere = V= 4/3 pi r 3 Volume of Cylinder = V=pi r 2 H Volume of Box = V= (l)(w)(h) Percent Eror = %Error = |VExp – Vst |/ Vst X 100% Density = P=M/V Procedure: 1. As a group, we first determined the masses per each individual object being measured in the experiment (Block, cylinders, spheres) with a triple beam balance scale, and used the table provided to track unit information. 2. We then utilized the digital Vernier Caliper to measure the length, width, and height of the rectangular block in centimeters and inches, as well as the length and height of the spheres & cylinders in centimeter and inches.
3. The Vernier Caliper was also used to determine the height and diameter of spheres needed to find the radius to complete the volume formulas. 4. The diameter and volumes of each object was calculated in order to produce a graph of Length(cm) vs. Length (in) and Volume (cm 3 ) vs. Volume (in 3 ).

Conclusion: While measuring the objects my group encountered problems such as the measurement sticks not defining inches or centimeters though this problem was quickly troubleshooted to further the lab advancement, and after plotting points for the graph, the slope for the second graph did not exactly match y=16x. Answers to Textbook Questions: 1) 1 g/cm^3 = 1000 kg/m^3. 2) Height of water = 1033.6 cm (H=76cm * 13600 kg/m 3 ÷ 1000 Kg/m 3 ) 3) 6.708 x 10 8 mi/hr. 4) 1 hour = 3,600 seconds
